Scenario
A user is clearly active in Teams, but coworkers only see the status as offline or unknown.
Recommended Resolution Path
- Confirm the account signs in cleanly to the Teams web app and desktop app.
- Check whether the device is failing to register with Exchange or Teams presence services due to proxy or firewall filtering.
- Clear the Teams cache and verify the workstation time is correct.
- If the issue follows the user across devices, inspect licensing and backend service health before deeper client work.
Technician Notes
Document what changed, what confirmed the fix, and whether the issue points to a broader standards gap worth addressing for the client.
